Hertfordshire County Council

We are the Lead Local Flood Authority (LLFA) and manage the risk of local flooding in Hertfordshire.

Our role

As the designated authority, our role within Hertfordshire is to develop a strategy where we monitor the local flood risk in the area.

We also establish and maintain a record of structures, such as walls or embankments, likely to have a significant effect on flood risk, including their ownership and state of repair. These are identified in a Flood Risk Asset Register.

To put any assets forward, please contact the Flood Risk Management Team:


Local flood risk management strategy for Hertfordshire

We have developed a Local Flood Risk Management Strategy that focuses on identifying and handling local flood risk from surface water, groundwater and ordinary watercourses, such as streams, ditches and small rivers.
